Soda blasting is much like conventional media or sand blasting, but instead
industrial-grade sodium bicarbonate powder to do the same job. It does a
very good job at removing paint and light rust, areas with deeper or more
rooted rust need to be spot-blasted with conventional medias or sand after
the soda blasting.
Why not just sand blast to begin with? Soda blasting has no chance of
warping body panels, it does not gouge the surface of the metal either like
sand can. It also leaves a slight film on the surface of the blasted metal
that is a good temporary rust preventative until you get the car cleaned and
into primer.
Wire brushing can get rust off a panel, but rarely ever removes all of the
rust at the surface of the metal, wire brushes have a difficult time getting
into the small pits that rust forms. So it may look rust free, but it
probably is not entirely.
Last I knew, the sodium bicarbonate, once used for blasting has to be
disposed of... it cannot be recycled and blasted again. So filling up your
home blaster with baking soda is not a good idea, and the industrial grades
of this stuff have much larger and coarser grains than supermarket soda.
